METAL-ION COMPLEXATION OF NONCYCLIC POLY(OXYETHYLENE) DERIVATIVES .6. SOLID-SOLID-LIQUID 3 PHASE-TRANSFER CATALYSIS OF POLYMER-BOUND ACYCLIC POLY(OXYETHYLENE) DERIVATIVES - APPLICATIONS TO ORGANIC-SYNTHESIS

Phase-transfer catalysis of insoluble polystyrene-bound poly(oxyethylene) monomethyl ethers in the reactions of anhydrous inorganic salts with liquid substrates, which was previously developed for the iodide ion-exchange reactions, has been successfully applied to generation and reactions of dichlorocarbene, further displacement reactions, cocatalysis to fluoride ion catalysis, a Wittig reaction, and a reduction with NaBH4. Mechanism of the catalysis was discussed in terms of anion activation by soft oxonium ion formation. © 1979, American Chemical Society. All rights reserved.
